So yo have 4x and -2x, since you are thinking in eliminate then you have this equation>
Note that we dont put the x variable, since we are studying its coefficients in the equations system.
Solving for K, Gives us that K=2
So.
Multiplying the second equation by 2 results in
When you put them together, it gives you the following
and the final equation is
giving you the answer for y, that is
